AUTOMOBILE DOOR VENTILATOR Filed Jan. 16, 1936 s 11 if A 1 fig W (1%07776 Patented June 22, 1937 iiNHTED STATES PATENT OFFIQE AUTOMOBILE DOOR VENTILATOR Application January 16, 1936, Serial No. 59,377

1 Claim.

My present invention relates to ventilators, and more particularly to automobile door venti lators.

More particularly my present invention relates to anti-draft ventilation between the upper front door frame and the glass sash to the effect that the interior of an automotive vehicle may be ventilated from the inside to the outside without producing a draft from the outside to the in side of the vehicle.

The principal object of my invention is an automobile door ventilator;

Another object is an automobile door frame having a curved draft guard adapted to admit air around the partially lowered sash to the outside of the vehicle;

Other objects and novel features comprising the construction and operation of my device will appear as the discription of thesame progresses.

Referring to the drawing illustrating the preferred embodiment of my invention,

Fig. 1 is an inside elevation of an automobile door to which my invention has been applied;

Fig. 2 is a fragmentary elevation of a portion of the door shown in Fig. 1 on a reduced scale and showing the glass sash partially lowered with the ventilator in an operating position;

Fig. 3 is a cross-section taken on the line 33 of Fig. 1 showing the sash closed, and

Fig. 4 is a cross-section taken on the line 44 of Fig. 2 but drawn to the same scale as Fig. 3 and showing the sash partially lowered as in Fig. 2.

Referring more in detail to the drawing, Fig. 1 illustrates a curved top automobile door to which my present invention has been applied, the disclosed sash raising mechanism being the subject matter of my co-pending applications Curved sash automobile door, filed Jan. 16, 1936, Ser. No. 59,375 and Automobile window sliding lock, filed Jan. 16, 1936, Ser. No. 59,376 now Patent No. 2,066,286.

Numeral Ill indicates a curved door frame having a conventional outer flanged area II and a body portion 12. It will be noted that the opening l3 has a slightly different curve from the edge of the glass sash I l which is shown in dotted lines in Fig. 1 in its fully elevated position, the opening l3 being eccentric to the curved sash edge. When the sash i4 is lowered slightly as shown in Fig. 2 the left-hand upper portion of the glass opens away from the opening IS in the door frame leaving an opening formed like a crescent through which air may pass while at the same time the rest of the sash is still engaged in the body of the door frame.

On the outside of the door frame in the same plane with the flanged portion II I have provided an anti-draft guard 15 having the same curved contour as the glass sash at this point, such that when the sash I4 is lowered slightly an air passage is presented around the edge of the glass sash and between that portion of the sash and the guard 15 as shown by the arrow in Fig. 4. The guard is located on the front edge of the door and the air flow when the automobile is in motion is from left to right. The sash acts as a bafile against the air which would normally tend to curve around the door frame and enter the sash opening and directs it along the sash from left to right thereby setting up a suction action in the opening between the sash and the door frame withdrawing the air from the interior of the vehicle as shown by the direction arrow in Fig. 4.

The sash I4 is raised and lowered in a vertical plane in the door frame as fully disclosed in aforesaid co-pending application Curved sash automobile door but the curve of the top of the sash is concentric in outline as compared with the opening 13 of the door and if desired can be used without the draft guard IS. The opening between the glass sash l4 and the door frame is obtained with an absolutely vertical movement of the sash in the frame of the door.

In Fig. 1 I have shown a semi-circular top door but the right-hand side of the door may, if desired, be substantially square instead of curved it being only necessary that the front edge or the back as the case may be is curved and that the curve of the glass be eccentric in position to the opening in the door.

With a construction of this kind it will be apparent that the curve of the door opening should be swung on a shorter radial curve from that of the rim of the sash and I may even use curved openings in the door which are not truly radial, the controlling element being in any event that a portion of the sash on one side or the other must enter the door frame further than that portion adapted to act as a ventilating opening when the sash is lowered for the purpose.

When the sash is fully raised the glass sash entirely closes the opening 13 in the door frame as shown in Fig. 1.

Having thus disclosed my invention what I claim as new is:

A vehicle window having a frame forming an opening with a curved forward edge, a panel slidable in its plane for closing said opening, said panel having a curved forward edge of greater radius of curvature than the curvature of said frame, and a ventilator guard rigidly attached to the forward edge of the frame and being parallel to and spaced outwardly from the forward edge of the panel.
